Cube the pork belly and pork tenderloin into bite-sized pieces and season with sea salt and black pepper.
In a small bowl, whisk together the gochujang, coconut aminos, and rice vinegar until smooth.
Place the pork belly in a cold skillet over medium heat, allowing the fat to render as the pan warms up until crispy.
Add the pork tenderloin to the skillet and sauté for 5-6 minutes until cooked through and golden brown.
Pour the gochujang sauce over the pork, stirring constantly for 1 minute until the meat is thoroughly glazed and sticky.
Remove the meat from the pan and quickly sauté the cauliflower rice in the remaining juices for 3 minutes until tender.
In a separate small non-stick pan, lightly grease with sesame oil and fry the egg until the whites are set but the yolk remains runny.
Assemble the bowl by layering the cauliflower rice, glazed pork, kimchi, and sliced cucumbers.
Top with the fried egg, toasted sesame seeds, and thinly sliced green onions.
